NAME

amzfs-sendrecv - Amanda script to create zfs sendrecv

DESCRIPTION

amzfs-sendrecv is an Amanda application implementing the Application
API. It should not be run by users directly. It create a zfs snapshot
of the filesystem and backup the snapshot with ´zfs send´. Snapshot are
kept after the backup is done, this increase the disk space use on the
client but it is neccesary to be able do to incremental backup. If you
want only full backup, you can disable this feature by setting the
KEEP-SNAPSHOT property to ´NO´. Only the restoration of the complete
backup is allowed, it is impossible to restore a single file.
The application is run as the amanda user, it must have many zfs
priviledge:
zfs allow -ldu AMANDA_USER mount,create,rename,snapshot,destroy,send,receive FILESYSTEM
Some system doesn´t have "zfs allow", but you can give the Amanda
backup user the rights to manipulate ZFS filesystems by using the
following command:
usermod -P "ZFS File System Management,ZFS Storage Management" AMANDA_USER
This will require that your run zfs under pfexec, set the PFEXEC
property to YES.
The format of the DLE must be one of:
Desciption Example
---------- -------
Mountpoint /data
ZFS pool name datapool
ZFS filesystem datapool/database
ZFS logical volume datapool/dbvol
The filesystem doesn´t need to be mounted.

ZFS-PATH
Path to the ´zfs´ binary, search in $PATH by default.
PFEXEC-PATH
Path to the ´pfexec´ binary, search in $PATH by default.
